Omega hangs periodically. Need help debugging

[Kostiantyn Tarasenko]

Hi, from time to time, like once per week my omega hangs (all lights are on still). Where can I find some logs to check or so?
Thanks

I'm seeing the same problem. Interesting spin is that I have the OLED expansion, so I can see that sometimes my cron job keeps running (just the ssh server hangs) and sometimes the cron job stops too.

The logs are in the kernel buffer, access through logread, but if the ssh server is hung I can't get in to see them.
